<p>openssl/core_dispatch.h - OpenSSL provider dispatch numbers and function types</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code> #include &lt;openssl/core_dispatch.h&gt;</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>The <i>&lt;openssl/core_dispatch.h&gt;</i> header defines all the operation numbers, dispatch numbers and provider interface function types currently available.</p>

<p>The operation and dispatch numbers are represented with macros, which are named as follows:</p>

<dl>

<dt id="operation-numbers">operation numbers</dt>
<dd>

<p>These macros have the form <code>OSSL_OP_<i>opname</i></code>.</p>

</dd>
<dt id="dipatch-numbers">dipatch numbers</dt>
<dd>

<p>These macros have the form <code>OSSL_FUNC_<i>opname</i>_<i>funcname</i></code>, where <code><i>opname</i></code> is the same as in the macro for the operation this function belongs to.</p>

</dd>
</dl>

<p>With every dispatch number, there is an associated function type.</p>

<p>For further information, please see the <a href="../man7/provider.html">provider(7)</a></p>
